Description

Technical Field

[0001] This utility model relates to the field of hair removal device technology, and in particular to a hair removal device handpiece and hair removal device. Background Technology

[0002] When a hair removal device is in operation, the light-emitting component releases a significant amount of heat. Current heat dissipation methods for hair removal devices mainly include water cooling and air cooling. Currently, water cooling often involves the coolant flowing directly over the light-emitting component to remove heat. However, because there is a certain distance between the light-emitting component and the light-transmitting component, the light emitted by the light-emitting component passes through the coolant before reaching the light-transmitting component, resulting in energy loss. This significantly reduces the hair removal effect of the device. To ensure the hair removal effect, a high-power light-emitting component is needed to compensate for the energy loss. The high power requirement inevitably increases the size of the hair removal device, limiting its practical use to large-scale equipment in professional institutions and making it difficult to achieve a miniaturized setup for home use. Utility Model Content

[0008] Preferably, the first filter and the inner wall of the light source slot enclose and define a light source cavity, the light-emitting element is located inside the light source cavity, and the light source cavity does not contain liquid.

[0009] Preferably, the semiconductor cooling chip includes a cooling surface and a heat dissipation surface opposite to each other, and the cooling surface is in contact with the light-transmitting element.

[0010] Preferably, the light source bracket has a water passage hole that connects the water passage channel and the liquid passage chamber.

[0011] Preferably, a water nozzle is provided at the end of the light source bracket away from the light-emitting element, and the water nozzle is in communication with the liquid passage cavity.

[0012] Preferably, the water nozzle includes an inlet nozzle and an outlet nozzle, and the liquid passage chamber is provided with a partition, which divides the liquid passage chamber into an inlet chamber and an outlet chamber corresponding to the inlet nozzle and the outlet nozzle, and the inlet chamber and the outlet chamber are connected through the water passage channel.

[0013] Preferably, there are two thermoelectric coolers, which are respectively disposed on opposite sides of the light-transmitting element. A limiting member is provided between the clamping blocks. The limiting member is in contact with the side of the light-transmitting element and the thermoelectric cooler.

[0020] Preferably, the exposed end is detachably fitted with a second filter.

[0021] Another solution to the technical problem of this utility model is to provide a hair removal device, which includes a heat dissipation component and a handpiece, wherein the heat dissipation component is connected to the liquid passage chamber.

[0022] Compared with the prior art, the hair removal handpiece and hair removal device of this utility model have the following advantages: 1. This utility model discloses a hair removal handpiece, comprising a main body and a light-emitting mechanism. The light-emitting mechanism is disposed within the main body and includes a light-emitting element and a light source support. The light source support is hollow, forming a liquid-passing cavity. The direction in which the light emitted from the main body is defined as the light-emitting direction. The surface of the light source support facing the light-emitting direction is recessed into the liquid-passing cavity to form a light source groove. The light source groove forms a raised portion within the liquid-passing cavity, and the light-emitting element is disposed within the light source groove. By recessing the surface of the light source support facing the light-emitting direction into the liquid-passing cavity to form a light source groove, and accommodating the light-emitting element within the light source groove, the light-emitting element is separated from the liquid-passing cavity through the light source groove. This allows the coolant to flow through the liquid-passing cavity, carrying away the heat conducted from the light-emitting element through the light source groove from the cavity surface without directly contacting the light-emitting element to dissipate heat. The liquid-passing cavity is located on the side away from the light-emitting direction, effectively avoiding the problem of energy loss of the light emitted by the light-emitting element due to the coolant directly flowing through it. The surface of the light source bracket facing the light emission direction is recessed into the liquid passage cavity to form a light source groove. The light source groove forms a raised part in the liquid passage cavity. Due to its raised shape, the contact area between the light source groove and the liquid passage cavity can be effectively increased, so that the heat of the light-emitting element can be conducted to the liquid passage cavity over a larger area, improving the heat dissipation efficiency. While ensuring heat dissipation efficiency, since the coolant does not flow directly through the light path between the light-emitting element and the light-transmitting element, there is no energy loss caused by the light passing through the coolant. Therefore, it is not necessary to increase the light emission power to compensate for the energy loss. The reduction in the light emission power requirement reduces the size requirement of the hair removal device handpiece, enabling the hair removal device handpiece to be miniaturized for home use.

[0023] 2. The light source slot of this utility model is equipped with a reflector cup, which is attached to the inner wall of the light source slot. The reflector cup forms a groove with its opening facing the light emission direction, and the light-emitting element is disposed in the groove. This arrangement ensures that even if the light emitted by the light-emitting element is not emitted in the light emission direction, it can still be emitted along the light emission direction through refraction by the reflector cup. This allows the light emitted by the light-emitting element to be utilized efficiently, maximizing its emission direction and thus improving the hair removal efficiency of the hair removal device.

[0024] 3. The light-emitting element of this utility model is a pulsed xenon lamp, which includes an anode, a cathode, and a trigger electrode. The anode and cathode are located at opposite ends of the pulsed xenon lamp, and the trigger electrode is located between the anode and cathode. By configuring the pulsed xenon lamp with three electrodes—an anode, a cathode, and a trigger electrode—an external triggering method can be used to achieve a better triggering effect.

[0025] 4. The lighting mechanism of this utility model further includes a first filter and a light-transmitting element. The first filter and the light-transmitting element are sequentially arranged on the side of the light-emitting element facing the light-emitting direction. By sequentially arranging the first filter and the light-transmitting element on the side of the light-emitting element facing the light-emitting direction, the light emitted by the light-emitting element is filtered by the first filter and then emitted through the light-transmitting element, so that the output spectrum of the light emitted from the light-transmitting element meets the hair removal requirements, and the unsuitable spectrum can be filtered out to achieve the hair removal effect.

[0026] 5. The first filter element and the inner wall of the light source slot of this utility model enclose and define a light source cavity, and the light-emitting element is located inside the light source cavity. The light source cavity does not contain liquid. Compared with the conventional water-cooled structure of the light source, the absence of liquid in the light source cavity can avoid energy loss when the light-emitting ray of the light-emitting element passes through the coolant due to the coolant flowing through the light source cavity, and also improves the safety of preventing leakage.

[0027] 6. At least one side of the light-transmitting element of this invention, parallel to the light emission direction, is provided with a semiconductor cooling chip. The semiconductor cooling chip includes opposing cooling and heat dissipation surfaces, with the cooling surface in contact with the light-transmitting element. By providing a semiconductor cooling chip on at least one side of the light-transmitting element parallel to the light emission direction, and with the cooling surface of the semiconductor cooling chip in contact with the light-transmitting element, the heat from the light-transmitting element can be efficiently and quickly transferred away through the semiconductor cooling chip, preventing burns to the user and damage to the hair removal device handpiece due to excessively high temperatures caused by the inability to dissipate heat in time.

[0028] 7. The semiconductor cooling chip of this invention has a clamping block on the side away from the light-transmitting element. A water-passing channel is formed within the clamping block, and the light source support has a water-passing hole connecting the water-passing channel and the liquid-passing cavity. By providing a clamping block with an internal water-passing channel on the side of the semiconductor cooling chip away from the light-transmitting element, the heat from the heat dissipation surface of the semiconductor cooling chip can be quickly conducted to the clamping block, and then carried away by the coolant in the water-passing channel. The light source support has a water-passing hole corresponding to the water-passing channel, which connects the water-passing channel and the liquid-passing cavity. This forms a circulation path, allowing the coolant in the liquid-passing cavity to not only promptly carry away the heat from the light-emitting element that is conducted through the light source slot to the surface of the liquid-passing cavity, but also further carry away the heat from the clamping block along the water-passing hole and water-passing channel, thus improving the cooling effect of the semiconductor cooling chip.

[0029] 8. The light source bracket of this utility model has a water nozzle at the end away from the light-emitting component, and the water nozzle is connected to the liquid passage chamber. By setting the water nozzle connected to the liquid passage chamber, the coolant in the liquid passage chamber can circulate with the external cooling device through the water nozzle, thereby further improving the heat dissipation effect of the coolant.

[0030] 9. The water nozzle of this utility model includes an inlet nozzle and an outlet nozzle. A partition is provided in the liquid passage chamber, which divides the liquid passage chamber into an inlet chamber and an outlet chamber corresponding to the inlet nozzle and the outlet nozzle. By setting two water nozzles, an outlet nozzle and an outlet nozzle, and dividing the liquid passage chamber into an inlet chamber and an outlet chamber corresponding to the inlet nozzle and the outlet nozzle, respectively, and connecting the inlet chamber and the outlet chamber through a water passage channel, the internal space of the liquid passage chamber is further subdivided. This ensures that the coolant enters the inlet chamber from the inlet nozzle, returns to the outlet chamber through the water passage, and then flows out from the outlet nozzle through the outlet chamber to complete the coolant circulation. This prevents the coolant from flowing in through the inlet nozzle and directly flowing out through the outlet nozzle without passing through the water passage channel, thus preventing the heat from the semiconductor cooling chip from being carried away. This achieves the beneficial effect of effectively ensuring that the heat at the light-emitting component and the light-transmitting component can be dissipated in a timely manner.

[0031] 10. This utility model includes two semiconductor cooling chips, which are respectively disposed on opposite sides of the light-transmitting element. A limiting member is provided between the clamping blocks, and the limiting member is in contact with the sides of the light-transmitting element and the semiconductor cooling chip. The clamping blocks are provided with connecting members, and the limiting members are connected to the clamping blocks via the connecting members. By providing limiting members on opposite sides of the light-transmitting element, the limiting members are made to fit against the light-transmitting element, and the limiting members are connected to the clamping blocks using the connecting members. This allows the light-transmitting element to be tightly fixed within the space enclosed by the limiting blocks and the clamping blocks, thus providing a fixed position and surrounding protection for the light-transmitting element.

[0032] 11. The limiting member of this utility model has wire grooves at two corners near the light-emitting element. By creating wire grooves at the two corners near the light-emitting element of the limiting member, the wires of the semiconductor cooling chip can be placed in the wire grooves, which not only restricts the position of the wires but also facilitates the connection of the wires through the limiting member to the semiconductor cooling chip.

[0033] 12. In this utility model, one side of the limiting component and the light-transmitting component that are close to each other is provided with a groove, and the other side is provided with a corresponding locking block. By providing corresponding grooves and locking blocks on the sides of the light-transmitting component and the limiting component that are close to each other, the light-transmitting component and the limiting component can be locked together, making the positional relationship between the light-transmitting component and the limiting component more stable, fixing the position of the light-transmitting component, and preventing the light-transmitting crystal from accidentally falling off.

[0034] 13. The light source bracket of this utility model has at least one side with a light source groove including a thermally conductive and insulating surface. By ensuring that at least one side of the light source bracket with a light source groove includes a thermally conductive and insulating surface, the light source groove can efficiently transfer heat to the liquid-passing cavity side using its excellent thermal conductivity, and also provides insulation, thus improving the safety of the hair removal device handpiece.

[0035] 14. The thermally conductive and insulating surface of this utility model is a ceramic surface, or the light source bracket is a ceramic bracket. Ceramic is a typical example of a thermally conductive and insulating material. Due to the low coefficient of linear expansion of ceramic material, the temperature of the hair removal device handpiece changes significantly between working and non-working states. The ceramic surface of the ceramic bracket, with its good dimensional stability, ensures dimensional stability even under large temperature differences, thus stabilizing the light-emitting mechanism structure. Furthermore, the ceramic material has good insulation properties, improving the safety of using the hair removal device handpiece.

[0036] 15. In this utility model, a gap is left between the first filter element and the light-transmitting element, and the lighting mechanism also includes a sealing element that seals the gap. By setting the sealing element to seal the gap between the first filter element and the light-transmitting element, a sealed space is formed. This avoids the light emitted by the light-emitting element being lost due to energy reduction caused by condensation of gas near the first filter element and the light-transmitting element when it cools and liquefies in the gap, thus further improving the light emission effect.

[0037] 16. The light-transmitting component of this utility model includes an exposed end, which is exposed on the outside of the main body. By providing an exposed end and exposing it on the outside of the main body, the exposed end can extend out of the main body and directly contact the skin for cold compress, effectively reducing the burning sensation on the skin caused by the light emitted by the light-emitting component.

[0038] 17. The exposed end of this utility model is detachably fitted with a second filter. By setting the second filter, the light emitted by the light-emitting element can be filtered again by the second filter after passing through the first filter and the light-transmitting element, making it more in line with the specific spectral requirements of the emitted light. At the same time, the detachable design allows the second filter to be installed or removed as needed, flexibly adjusting the filtering requirements.

[0039] 18. This utility model also provides a hair removal device, which has the same beneficial effects as the hair removal device handpiece mentioned above, and will not be described in detail here. Attached Figure Description

Detailed Implementation

[0051] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0052] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0054] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0055] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0056] Please combine Figures 1 to 4 The first embodiment of this utility model provides a hair removal handpiece 1, including a main body 20 and a light-emitting mechanism 30. The light-emitting mechanism 30 is disposed in the main body 20 and includes a light-emitting element 31 and a light source support 32. The light source support 32 is hollow to form a liquid passage cavity 321. The direction in which the light emitted by the light-emitting element 31 from the main body 20 is defined as the light emission direction. The side surface of the light source support 32 facing the light emission direction is recessed into the liquid passage cavity 321 to form a light source groove 322. The light source groove 322 forms a raised part 3221 in the liquid passage cavity 321, and the light-emitting element 31 is disposed in the light source groove 322.

[0057] Understandably, through the above structural arrangement, the surface of the light source bracket 32 ​​facing the light emission direction is recessed into the liquid passage cavity 321 to form a light source groove 322, and the light-emitting element 31 is housed within the light source groove 322. The light source groove 322 separates the light-emitting element 31 from the liquid passage cavity 321, allowing the coolant to flow through the liquid passage cavity 321 and carry away the heat conducted from the light-emitting element 31 through the light source groove 322 from the cavity surface of the liquid passage cavity 321, without directly contacting the light-emitting element 31 to dissipate its heat. The liquid passage cavity 321 is located on the side away from the light emission direction of the light-emitting element 31, so the light emitted by the light-emitting element 31 will not pass through the coolant in the liquid passage cavity 321, effectively avoiding the problem of energy loss of the light emitted by the light-emitting element 31 in the coolant due to the coolant directly flowing through it. The surface of the light source bracket 32 ​​facing the light emission direction is recessed into the liquid passage cavity 321 to form a light source groove 322. The light source groove 322 forms a raised portion 3221 within the liquid passage cavity 321. Due to its raised shape, the raised portion 3221 can effectively increase the contact area between the light source groove 322 and the liquid passage cavity 321, allowing the heat from the light-emitting element 31 to be conducted to the liquid passage cavity 321 over a larger area, thus improving heat dissipation efficiency. With the above structural design, while ensuring heat dissipation efficiency, since the coolant does not flow directly through the light path between the light-emitting element 31 and the light-transmitting element 35, there is no energy loss caused by light passing through the coolant. Therefore, it is not necessary to increase the luminous power to compensate for the energy loss. Thus, a lower luminous power can meet the standard luminous power requirement of the light-emitting element 31. The reduction in luminous power requirement means that the hair removal device handpiece 1 does not need to be enlarged to accommodate the high-power light-emitting element 31. The hair removal device handpiece 1 can be miniaturized for home use, expanding the application scenarios of the hair removal device handpiece 1.

[0058] Furthermore, as one embodiment, at least one side of the light source support 32 where the light source groove 322 is located includes a thermally conductive and insulating surface. By ensuring that at least one side of the light source support 32 where the light source groove 322 is located includes a thermally conductive and insulating surface, the light source groove 322 can efficiently transfer heat to the liquid cavity 321 side using its good thermal conductivity, and also provides insulation, thereby improving the safety of the hair removal device handpiece 1.

[0059] In a preferred embodiment, the thermally conductive and insulating surface is a ceramic surface, or the light source support 32 is a ceramic support. Understandably, due to the low coefficient of linear expansion of ceramic material, the temperature of the hair removal device 1 changes significantly when it is in operation versus when it is not in operation. The ceramic surface of the ceramic support, with its good dimensional stability, ensures that it does not deform significantly under large temperature differences, thus ensuring the structural stability of the light-emitting mechanism 30. Simultaneously, the high thermal conductivity of ceramic material efficiently conducts the heat generated by the light-emitting element 31 to the liquid cavity 321, thereby improving heat dissipation efficiency. Ceramic material also has good insulation properties, improving the safety of using the hair removal device 1.

[0060] Please combine Figure 3 and Figure 4 Furthermore, a reflector cup 33 is provided inside the light source groove 322. The reflector cup 33 is attached to the inner wall of the light source groove 322. The reflector cup 33 forms a groove 331 with the cup opening facing the light emission direction. The light-emitting element 31 is disposed inside the groove 331.

[0061] Understandably, the initial light emission direction of the light-emitting element 31 is not always towards the light-emitting direction. By setting a reflector cup 33 in the light source slot 322, and forming a cup groove 331 with the cup opening facing the light-emitting direction, the light emitted by the light-emitting element 31 can still be emitted along the light-emitting direction through the refraction of the reflector cup 33, so that the light emitted by the light-emitting element 31 can be used efficiently and emitted from the light-emitting direction as much as possible, thereby improving the hair removal efficiency of the hair removal device 1.

[0062] Please combine Figure 3 and Figure 5 Furthermore, the lighting mechanism 30 also includes a first filter element 34 and a light-transmitting element 35, and the first filter element 34 and the light-transmitting element 35 are arranged sequentially on the side of the light-emitting element 31 facing the light-emitting direction.

[0063] Understandably, by sequentially arranging a first filter element 34 and a light-transmitting element 35 on the side of the light-emitting element 31 facing the light-emitting direction, the light emitted by the light-emitting element 31 is filtered by the first filter element 34 and then emitted through the light-transmitting element 35, so that the output spectrum of the light emitted from the light-transmitting element 35 meets the hair removal requirements and can filter out the spectrum that does not meet the requirements to achieve the hair removal effect.

[0064] Optionally, the light-transmitting element 35 may be made of any one of sapphire crystal, quartz glass, or K9 glass.

[0065] Furthermore, please combine Figure 3 and Figure 4The first filter element 34 and the inner wall of the light source groove 322 enclose and define a light source cavity 3222. The light-emitting element 31 is located in the light source cavity 3222. The light source cavity 3222 does not contain liquid. Compared with the conventional water-cooled structure of the light source, the light source cavity 3222 does not contain liquid, which can avoid the energy loss of the light-emitting line of the light-emitting element 31 when passing through the coolant due to the coolant flowing through the light source cavity 3222. It also improves the safety of preventing leakage.

[0066] Please combine Figure 2 , Figure 3 and Figure 5 Furthermore, the light-transmitting element 35 includes an exposed end 352, which is exposed on the outside of the main body 20.

[0067] Understandably, the light-transmitting element 35 is provided with an exposed end 352 and the exposed end 352 is exposed to the outside of the main body 20, so that the exposed end 352 can extend out of the outside of the main body 20 and directly contact the skin for cold compress, which can effectively reduce the burning sensation on the skin caused by the light emitted by the light-emitting element 31.

[0068] Please continue to combine Figure 2 , Figure 3 and Figure 5 Furthermore, the exposed end 352 is detachably fitted with a second filter element 3521.

[0069] Understandably, by setting the second filter element 3521, the light emitted by the light-emitting element 31 can be filtered again by the second filter element 3521 after passing through the first filter element 34 and the light-transmitting element 35, making it more in line with the specific spectral requirements of the emitted light. At the same time, the detachable sleeve design allows the second filter to be installed or removed according to actual needs, flexibly adjusting the filtering requirements.

[0070] Specifically, the second filter 3521 can be replaced with various models that filter different wavelengths. Replacing the second filter 3521 with different models can achieve more functions such as whitening and acne removal, further meeting the users' broader phototherapy needs.

[0071] Please combine Figures 3 to 5 Furthermore, a sealing element 341 is provided between the first filter element 34 and the light-transmitting element 35, and the first filter element 34, the light-transmitting element 35 and the sealing element 341 together form a sealed space.

[0072] A gap 342 is left between the first filter element 34 and the light-transmitting element 35. The lighting mechanism 30 also includes a sealing element 341, which seals the gap 342.

[0073] Understandably, by setting the sealing element 341 to seal the gap 342 between the first filter element 34 and the light-transmitting element 35, the gas near the first filter element 34 and the light-transmitting element 35 is prevented from condensing and remaining in the gap 342 between the first filter element 34 and the light-transmitting element 35 due to cooling. This prevents the light emitted by the light-emitting element 31 from being depleted by the condensed liquid when passing through the gap 342, thus further improving the light emission effect. At the same time, it can also prevent the accumulation of condensate water from flowing out and causing electrical conductivity, which could lead to safety accidents.

[0074] Please combine Figure 3 and Figure 5 Furthermore, a water nozzle 324 is provided at the end of the light source bracket 32 ​​away from the light-emitting element 31, and the water nozzle 324 is connected to the liquid passage cavity 321.

[0075] Understandably, by setting a water nozzle 324 connected to the liquid passage chamber 321, the coolant in the liquid passage chamber 321 can circulate with the external cooling device through the water nozzle 324, thereby further improving the heat dissipation effect of the coolant.

[0076] Specifically, in one embodiment, the water tap 324 includes an inlet tap 3241 and an outlet tap 3242. The liquid passage chamber 321 is provided with a partition 3211, which divides the liquid passage chamber 321 into an inlet chamber 3212 and an outlet chamber 3213 corresponding to the inlet tap 3241 and the outlet tap 3242. The inlet chamber 3212 and the outlet chamber 3213 are connected through the water passage 371 inside the polishing mechanism 30.

[0077] Understandably, by setting an outlet nozzle 3242 and an inlet nozzle 3241, and dividing the liquid passage chamber 321 into an inlet chamber 3212 and an outlet chamber 3213 corresponding to the inlet nozzle 3241 and the outlet nozzle 3242 by a partition 3211, and connecting the inlet chamber 3212 and the outlet chamber 3213 through a water passage 371, the internal space of the liquid passage chamber 321 is further subdivided. This ensures that after the coolant enters the inlet chamber 3212 from the inlet nozzle 3241, it returns to the outlet chamber 3213 through the water passage 371, and then flows out from the outlet nozzle 3242 through the outlet chamber 3213 to complete the coolant circulation. This prevents the coolant from flowing in through the inlet nozzle 3241 and then directly flowing out through the outlet nozzle 3242 without passing through the water passage 371, thus preventing the heat from the semiconductor cooling chip 36 from being carried away. This achieves the beneficial effect of effectively ensuring that the heat at the light-emitting element 31 and the light-transmitting element 35 can be dissipated in a timely manner.

[0078] Please combine Figure 3 , Figure 5 and Figure 6Furthermore, at least one side of the light-transmitting element 35 parallel to the light-emitting direction is provided with a semiconductor cooling chip 36. The semiconductor cooling chip 36 includes a cooling surface 361 and a heat dissipation surface 362, and the cooling surface 361 is attached to the light-transmitting element 35.

[0079] Understandably, by providing a semiconductor cooling chip 36 on at least one side of the light-transmitting element 35 parallel to the light-emitting direction, and having the cooling surface 361 of the semiconductor cooling chip 36 in contact with the light-transmitting element 35, the heat of the light-transmitting element 35 can be efficiently and quickly transferred out through the semiconductor cooling chip 36, preventing the problem of the user being burned and the hair removal device handpiece 1 being damaged due to the heat of the light-transmitting element 35 not being dissipated in time.

[0080] Please combine Figure 3 , Figures 5 to 7 Furthermore, a clamping block 37 is provided on the side of the semiconductor cooling chip 36 away from the light-transmitting element 35. A water passage 371 is formed in the clamping block 37, and a water passage hole 323 is formed on the light source support 32, connecting the water passage 371 and the liquid passage cavity 321. Specifically, water passage holes 323 are provided between the water passage 371 and the water inlet cavity 3212 and between the water passage 371 and the water outlet cavity 3213, so that the water passage holes 323 can connect the water passage 371 and the water inlet cavity 3212 and the water passage 371 and the water outlet cavity 3213, thereby forming an internal passage between the light source support 32 and the clamping block 37. The coolant flows from the water inlet cavity 3212 through the water hole 323 to the water passage 371, and then from the water passage 371 through the water hole 323 to the water outlet cavity 3213.

[0081] Understandably, by setting a clamping block 37 with an internal water passage 371 on the side of the semiconductor cooling chip 36 away from the light-transmitting element 35, the heat from the heat dissipation surface 362 of the semiconductor cooling chip 36 can be quickly conducted to the clamping block 37, and then the coolant in the water passage 371 carries away this heat. The light source bracket 32 ​​has a water passage hole 323 corresponding to the water passage 371. The water passage hole 323 connects the water passage 371 and the liquid passage cavity 321, so that the water passage hole 323, the water passage 371 and the liquid passage cavity 321 form a circulation path. The coolant in the liquid passage cavity 321 can not only carry away the heat from the light-emitting element 31 through the light source slot 322 and then conducted to the surface of the liquid passage cavity 321 in a timely manner, but also further carry away the heat from the clamping block 37 along the water passage hole 323 and the water passage 371, thereby improving the cooling effect of the semiconductor cooling chip 36.

[0082] Specifically, in one embodiment, there are two semiconductor cooling chips 36, which are respectively disposed on opposite sides of the light-transmitting element 35. A limiting member 38 is provided between the clamping blocks 37. The limiting member 38 is in contact with the side of the light-transmitting element 35 and the semiconductor cooling chip 36. The clamping block 37 is provided with a connecting member 372, and the limiting member 38 is connected to the clamping block 37 through the connecting member 372.

[0083] Understandably, by providing limiting members 38 on two opposite sides of the light-transmitting member 35, the limiting members 38 fit snugly against the light-transmitting member 35, and by using the connecting member 372 to connect the limiting members 38 to the clamping block 37, the light-transmitting member 35 can be tightly fixed within the space area enclosed by the limiting block and the clamping block 37, thus playing the role of fixing the position and surrounding protection of the light-transmitting member 35.

[0084] Please see Figure 5 Furthermore, one of the sides of the limiting member 38 and the light-transmitting member 35 that are close to each other is provided with a groove 351, and the other side is provided with a corresponding locking block 381.

[0085] Specifically, in one embodiment, the side of the light-transmitting member 35 is provided with a groove 351 on the side where the limiting member 38 and the light-transmitting member 35 are close to each other, and the side of the limiting member 38 is provided with a corresponding locking block 381; in another embodiment, the side of the limiting member 38 is provided with a groove 351 on the side where the limiting member 38 and the light-transmitting member 35 are close to each other, and the side of the light-transmitting member 35 is provided with a corresponding locking block 381.

[0086] Understandably, by providing corresponding grooves 351 and locking blocks 381 on the sides of the light-transmitting element 35 and the limiting element 38 that are close to each other, the light-transmitting element 35 and the limiting element 38 can be locked together, making the positional relationship between the light-transmitting element 35 and the limiting element 38 more stable, fixing the position of the light-transmitting element 35, and preventing the light-transmitting crystal from falling off accidentally.

[0087] Please combine Figure 5 and Figure 6 The limiting member 38 has wire grooves 382 at two corners near the end of the light-emitting member 31.

[0088] Understandably, by opening wire grooves 382 at the two corners of the limiting member 38 near the light-emitting member 31, the wires of the semiconductor cooling chip 36 can be placed in the wire grooves 382, ​​which restricts the position of the wires and facilitates the wires passing through the limiting member 38 and connecting to the semiconductor cooling chip 36.

[0089] Please combine Figure 3 , Figure 5 and Figure 8As an optional implementation, the light-emitting element 31 is a pulsed xenon lamp 311. The pulsed xenon lamp 311 includes an anode 3111, a cathode 3112, and a trigger electrode 3113. The anode 3111 and the cathode 3112 are disposed at both ends of the pulsed xenon lamp 311, and the trigger electrode 3113 is disposed between the anode 3111 and the cathode 3112.

[0090] It should be noted that the trigger electrode 3113 of the pulsed xenon lamp 311 can be either a wound wire or the pulsed xenon lamp 311 moving close to the reflector 33 to function as the trigger electrode 3113. Understandably, by configuring the pulsed xenon lamp 311 with three electrodes—anode 3111, cathode 3112, and trigger electrode 3113—an external triggering method can be used to achieve a better triggering effect.

[0091] Please see Figure 9 The second embodiment of this utility model provides a hair removal device 100, which includes a heat dissipation component 40 and a hair removal device handpiece 1. The heat dissipation component 40 is connected to the liquid passage chamber 321. Specifically, the heat dissipation component 40 can use a fan to cool the coolant circulating between the heat dissipation component 40 and the hair removal device handpiece 1, or it can use a heat exchanger for water cooling or air cooling to cool the coolant. By using the heat dissipation component 40 to circulate and dissipate the coolant in the hair removal device handpiece 1, the hair removal device 100 can maintain a long-term stable working state for hair removal operations.

[0092] Compared with the prior art, the hair removal handpiece and hair removal device of this utility model have the following advantages: 1. This utility model discloses a hair removal handpiece, comprising a main body and a light-emitting mechanism. The light-emitting mechanism is disposed within the main body and includes a light-emitting element and a light source support. The light source support is hollow, forming a liquid-passing cavity. The direction in which the light emitted from the main body is defined as the light-emitting direction. The surface of the light source support facing the light-emitting direction is recessed into the liquid-passing cavity to form a light source groove. The light source groove forms a raised portion within the liquid-passing cavity, and the light-emitting element is disposed within the light source groove. By recessing the surface of the light source support facing the light-emitting direction into the liquid-passing cavity to form a light source groove, and accommodating the light-emitting element within the light source groove, the light-emitting element is separated from the liquid-passing cavity through the light source groove. This allows the coolant to flow through the liquid-passing cavity, carrying away the heat conducted from the light-emitting element through the light source groove from the cavity surface without directly contacting the light-emitting element to dissipate heat. The liquid-passing cavity is located on the side away from the light-emitting direction, effectively avoiding the problem of energy loss of the light emitted by the light-emitting element due to the coolant directly flowing through it. The surface of the light source bracket facing the light emission direction is recessed into the liquid passage cavity to form a light source groove. The light source groove forms a raised part in the liquid passage cavity. Due to its raised shape, the contact area between the light source groove and the liquid passage cavity can be effectively increased, so that the heat of the light-emitting element can be conducted to the liquid passage cavity over a larger area, improving the heat dissipation efficiency. While ensuring heat dissipation efficiency, since the coolant does not flow directly through the light path between the light-emitting element and the light-transmitting element, there is no energy loss caused by the light passing through the coolant. Therefore, it is not necessary to increase the light emission power to compensate for the energy loss. The reduction in the light emission power requirement reduces the size requirement of the hair removal device handpiece, enabling the hair removal device handpiece to be miniaturized for home use.

[0093] 2. The light source tank of this utility model does not contain liquid. Compared with the conventional water-cooled structure of the light source tank, the light source tank does not contain liquid, which can avoid the energy loss of the light-emitting line of the light-emitting element when passing through the coolant due to the coolant flowing through the light source tank. It also improves the safety of preventing leakage.

[0094] 3. The light source slot of this utility model is equipped with a reflector cup, which is attached to the inner wall of the light source slot. The reflector cup forms a groove with its opening facing the light emission direction, and the light-emitting element is disposed in the groove. This arrangement ensures that even if the light emitted by the light-emitting element is not emitted in the light emission direction, it can still be emitted along the light emission direction through refraction by the reflector cup. This allows the light emitted by the light-emitting element to be utilized efficiently, maximizing its emission direction and thus improving the hair removal efficiency of the hair removal device.

[0095] 4. The light-emitting element of this utility model is a pulsed xenon lamp, which includes an anode, a cathode, and a trigger electrode. The anode and cathode are located at opposite ends of the pulsed xenon lamp, and the trigger electrode is located between the anode and cathode. By including an anode, cathode, and trigger electrode in the pulsed xenon lamp, an external triggering method can be used to achieve a better triggering effect.

[0096] 5. The lighting mechanism of this utility model further includes a first filter and a light-transmitting element, with the first filter and the light-transmitting element sequentially arranged on the side of the light-emitting element facing the light-emitting direction. By sequentially arranging the first filter and the light-transmitting element on the side of the light-emitting element facing the light-emitting direction, the light emitted by the light-emitting element is filtered by the first filter and then emitted through the light-transmitting element, so that the output spectrum of the light emitted from the light-transmitting element meets the hair removal requirements, and the unsuitable spectrum can be filtered out to achieve the hair removal effect.

[0097] 6. At least one side of the light-transmitting element of this invention, parallel to the light emission direction, is provided with a semiconductor cooling chip. The semiconductor cooling chip includes opposing cooling and heat dissipation surfaces, with the cooling surface in contact with the light-transmitting element. By providing a semiconductor cooling chip on at least one side of the light-transmitting element parallel to the light emission direction, and with the cooling surface of the semiconductor cooling chip in contact with the light-transmitting element, the heat from the light-transmitting element can be efficiently and quickly transferred away through the semiconductor cooling chip, preventing burns to the user and damage to the hair removal device handpiece due to excessively high temperatures caused by the inability to dissipate heat in time.

[0098] 7. The semiconductor cooling chip of this invention has a clamping block on the side away from the light-transmitting element. A water-passing channel is formed within the clamping block, and the light source support has a water-passing hole connecting the water-passing channel and the liquid-passing cavity. By providing a clamping block with an internal water-passing channel on the side of the semiconductor cooling chip away from the light-transmitting element, the heat from the heat dissipation surface of the semiconductor cooling chip can be quickly conducted to the clamping block, and then carried away by the coolant in the water-passing channel. The light source support has a water-passing hole corresponding to the water-passing channel, which connects the water-passing channel and the liquid-passing cavity. This forms a circulation path, allowing the coolant in the liquid-passing cavity to not only promptly carry away the heat from the light-emitting element that is conducted through the light source slot to the surface of the liquid-passing cavity, but also further carry away the heat from the clamping block along the water-passing hole and water-passing channel, thus improving the cooling effect of the semiconductor cooling chip.

[0099] 8. The light source bracket of this utility model has a water nozzle at the end away from the light-emitting component, and the water nozzle is connected to the liquid passage chamber. By setting the water nozzle connected to the liquid passage chamber, the coolant in the liquid passage chamber can circulate with the external cooling device through the water nozzle, thereby further improving the heat dissipation effect of the coolant.

[0100] 9. The water nozzle of this utility model includes an inlet nozzle and an outlet nozzle. A partition is provided in the liquid passage chamber, which divides the liquid passage chamber into an inlet chamber and an outlet chamber corresponding to the inlet nozzle and the outlet nozzle. By setting two water nozzles, an outlet nozzle and an outlet nozzle, and dividing the liquid passage chamber into an inlet chamber and an outlet chamber corresponding to the inlet nozzle and the outlet nozzle, respectively, and connecting the inlet chamber and the outlet chamber through a water passage channel, the internal space of the liquid passage chamber is further subdivided. This ensures that the coolant enters the inlet chamber from the inlet nozzle, returns to the outlet chamber through the water passage, and then flows out from the outlet nozzle through the outlet chamber to complete the coolant circulation. This prevents the coolant from flowing in through the inlet nozzle and directly flowing out through the outlet nozzle without passing through the water passage channel, thus preventing the heat from the semiconductor cooling chip from being carried away. This achieves the beneficial effect of effectively ensuring that the heat at the light-emitting component and the light-transmitting component can be dissipated in a timely manner.

[0101] 10. This utility model includes two semiconductor cooling chips, which are respectively disposed on opposite sides of the light-transmitting element. A limiting member is provided between the clamping blocks, and the limiting member is in contact with the sides of the light-transmitting element and the semiconductor cooling chip. The clamping blocks are provided with connecting members, and the limiting members are connected to the clamping blocks via the connecting members. By providing limiting members on opposite sides of the light-transmitting element, the limiting members are made to fit against the light-transmitting element, and the limiting members are connected to the clamping blocks using the connecting members. This allows the light-transmitting element to be tightly fixed within the space enclosed by the limiting blocks and the clamping blocks, thus providing a fixed position and surrounding protection for the light-transmitting element.

[0102] 11. The limiting member of this utility model has wire grooves at two corners near the light-emitting element. By creating wire grooves at the two corners near the light-emitting element of the limiting member, the wires of the semiconductor cooling chip can be placed in the wire grooves, which not only restricts the position of the wires but also facilitates the connection of the wires through the limiting member to the semiconductor cooling chip.

[0103] 12. In this utility model, one side of the limiting component and the light-transmitting component that are close to each other is provided with a groove, and the other side is provided with a corresponding locking block. By providing corresponding grooves and locking blocks on the sides of the light-transmitting component and the limiting component that are close to each other, the light-transmitting component and the limiting component can be locked together, making the positional relationship between the light-transmitting component and the limiting component more stable, fixing the position of the light-transmitting component, and preventing the light-transmitting crystal from accidentally falling off.

[0104] 13. The light source bracket of this utility model has at least one side with a light source groove including a thermally conductive and insulating surface. By ensuring that at least one side of the light source bracket with a light source groove includes a thermally conductive and insulating surface, the light source groove can efficiently transfer heat to the liquid-passing cavity side using its excellent thermal conductivity, and also provides insulation, thus improving the safety of the hair removal device handpiece.

[0105] 14. The thermally conductive and insulating surface of this utility model is a ceramic surface, or the light source bracket is a ceramic bracket. Ceramic is a typical example of a thermally conductive and insulating material. Due to the low coefficient of linear expansion of ceramic material, the temperature of the hair removal device handpiece changes significantly between working and non-working states. The ceramic surface of the ceramic bracket, with its good dimensional stability, ensures dimensional stability even under large temperature differences, thus stabilizing the light-emitting mechanism structure. Furthermore, the ceramic material has good insulation properties, improving the safety of using the hair removal device handpiece.

[0106] 15. In this utility model, a gap is left between the first filter element and the light-transmitting element, and the lighting mechanism also includes a sealing element that seals the gap. By setting the sealing element to seal the gap between the first filter element and the light-transmitting element, a sealed space is formed. This avoids the light emitted by the light-emitting element being lost due to energy reduction caused by condensation of gas near the first filter element and the light-transmitting element when it cools and liquefies in the gap, thus further improving the light emission effect.

[0107] 16. The light-transmitting component of this utility model includes an exposed end, which is exposed on the outside of the main body. By providing an exposed end and exposing it on the outside of the main body, the exposed end can extend out of the main body and directly contact the skin for cold compress, effectively reducing the burning sensation on the skin caused by the light emitted by the light-emitting component.

[0108] 17. The exposed end of this utility model is detachably fitted with a second filter. By setting the second filter, the light emitted by the light-emitting element can be filtered again by the second filter after passing through the first filter and the light-transmitting element, making it more in line with the specific spectral requirements of the emitted light. At the same time, the detachable design allows the second filter to be installed or removed as needed, flexibly adjusting the filtering requirements.

[0109] 18. This utility model also provides a hair removal device, which has the same beneficial effects as the hair removal device handpiece mentioned above, and will not be described in detail here.

[0110] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
